So is John Semmens....has been for more than a decade.
In fact in his source line he would ALWAYS write “semi-news/semi-satire”. I used to enjoy getting caught up in his writings. But about five years ago the mods started requiring him to put it in his headline thereby negating the desired effect of his satire while for the Babylon Bee that rule was not enforced.
Like I said, some authors are just more equal than others.
It is enforced. If one of the mods notices a babylon sourced article or if someone sends in an abuse report we flag it as satire.
